Analysis of body weights at the start and the end of the experiment largely confirmed these trends ( Figure 1 B; main effect of Time: F(1,86) = 1008.2, p < 0.001; main effect of Sex: F(1,86) = 163.0, p < 0.001; Time × Sex interaction: F(1,86) = 10.2, p = 0.002; Time x Genotype interaction: F(1,86) = 5.56, p = 0.021), although the effect of Meth on body weight gain failed to reach significance ( p = 0.055).
